ABSTRACT:
A lifting apparatus is provided that is especially designed for gripping and lifting oversized, heavy metal plate materials. Metal plates in a horizontal position may be lifted and deposited in upright disposition in a bin therefor, and then retrieved from such bin and returned to a horizontal location for use or work thereon. The apparatus includes first and second, opposed, hook-shaped grippers for abuttably engaging opposed marginal ends of a metal plate to be lifted, and a webbed belt reaved around the grippers in a manner to urge the grippers into plate engaging relationship. One of the two grippers includes guide structure that provides for selective engagement and disengagement of at least one of the grippers from a plate or plates thus facilitating insertion and removal of the apparatus from bin stored upright stacks of plates in closely spaced relationship.
